      Gawarkiewicz, Glen G.; Monismith, Stephen G.; Largier, John (Oceanography Society, 2007-09)
      Population connectivity is inherently bio-physical: it is determined by physical transport and dispersion, as well as biological processes such as timing of spawning, larval behavior, and mortality. Knowledge of ...

    • Occupational safety and regulatory compliance in US commercial fishing 

      Davis, Mary E. (2010-11-19)
      This study explored occupational safety practices and regulatory compliance in a representative sample of Maine commercial fishing vessels. Data were collected on demographic characteristics, safety equipment and training, ...
    • Ocean acidification 

      Unknown author (OCB Project Office, 2007-10)
      The goal of this workshop was to bring together researchers to discuss potential ocean acidification research projects that support the OCB mission. We specifically wanted to move toward specific implementation strategies ...
    • Ocean acidification : a critical emerging problem for the ocean sciences 

      Doney, Scott C.; Balch, William M.; Fabry, Victoria J.; Feely, Richard A. (Oceanography Society, 2009-12)
      Over a period of less than a decade, ocean acidification—the change in seawater chemistry due to rising atmospheric carbon dioxide (CO2) levels and subsequent impacts on marine life—has become one of the most critical ...
    • Ocean acidification : present conditions and future changes in a high-CO2 world 

      Feely, Richard A.; Doney, Scott C.; Cooley, Sarah R. (Oceanography Society, 2009-12)
      The uptake of anthropogenic CO2 by the global ocean induces fundamental changes in seawater chemistry that could have dramatic impacts on biological ecosystems in the upper ocean. Estimates based on the Intergovernmental ...
    • Ocean acidification in the surface waters of the Pacific-Arctic boundary regions 

      Mathis, Jeremy T.; Cross, Jessica N.; Evans, Wiley; Doney, Scott C. (The Oceanography Society, 2015-06)
      The continental shelves of the Pacific-Arctic Region (PAR) are especially vulnerable to the effects of ocean acidification (OA) because the intrusion of anthropogenic CO2 is not the only process that can reduce pH and ...
    • Ocean acidification not likely to affect the survival and fitness of two temperate benthic foraminiferal species : results from culture experiments 

      McIntyre-Wressnig, Anna; Bernhard, Joan M.; Wit, Johannes C.; McCorkle, Daniel C. (2014-10)
      Specimens of Bolivina argentea and Bulimina marginata, two widely distributed temperate benthic foraminiferal species, were cultured at constant temperature and controlled pCO2 (ambient, 1000 ppmv, and 2000 ppmv) for six ...

      The highly productive fisheries of Alaska are located in seas projected to experience strong global change, including rapid transitions in temperature and ocean acidification-driven changes in pH and other chemical parameters. ...
    • Ocean acidification’s potential to alter global marine ecosystem services 

      Cooley, Sarah R.; Kite-Powell, Hauke L.; Doney, Scott C. (Oceanography Society, 2009-12)
